AS AN AID TO REASSEMBLY, TAKE NOTICE OF WIRE ROUTING AND
POSITION IN WIRE GUIDES AND TRAPS WHILE DISMANTLING TOOL.
BE SURE THAT ALL COMPONENTS OF THE ELECTRONICS KIT ARE SEATED
FIRMLY AND SQUARELY IN THE HOUSING RECESSES.
AVOID PINCHED WIRES, BE SURE THAT ALL WIRES AND SLEEVES ARE

PRIOR TO INSTALLING THE HOUSING COVER ONTO THE HOUSING SUPPORT,
BE SURE THAT THERE ARE NO INTERFERENCES.
NOTE: #27b Battery Connector Block 22-56-0047 is service-able.
To preserve thewire lengths, it is not recommended tocut the wires
above the terminal block.
To remove thebattery connector block do the following: 1. The
hot glue or heat shrink tubing must be care- fully removed from
each wire by using a knife or razor blade.2. Carefully heat the
solder at the terminal location to remove each wire.3. Place a new
piece of heat shrink tubing over each wire prior to resoldering
onto the new Battery Connector Block.4. Be sure the wires are place
back at the correct terminal locations. Solder each wire back into
place. Slide heat shrink tubing over the solder/terminal area and
heat to secure. (Note: A small strip of electrical tape can be used
in place of heat shrink tubing).
